4.- Claims. 1

My invention relates to windows for factories and other buildings.

The objects of my invention are to provide a :form of window for either single or multiple sashes and with single or double panes of glass with each sash "so arranged and mounted upon pivotal means that it can be revolved upon its middle horizontal pivotal axis either through a whole circle or any part thereof and in either direction; to provide Windows both sides of which may be washed from the inside of the building and the danger of window washers falling While doing their work can be eliminated; to provide mean to prevent the entrance or movement of rain or wind between the window sashes and the Window frames; to provide means whereby the window sashes and their frames may be completely assembled and adjusted before belngset and the assemblies be readily'and firmly mounted in the walls of a building; to provide means whereby the window sashes may be revolved in either direction either manually or by use of a portable electric motor without disturbing the position of the frames in the walls; to provide windows of the class described suitable for use in high buildings for factories or other purposes.

I accomplish these objects by the means illus trated in the accompanying drawings in which,

Figure 1 is an inside elevation of a window having a plurality of sashes;

Figure 2 "is a vertical section on the line Z Z tar-Figure 1;

Figures is an enlarged sectional detail on the line 3+3 of Figure 1;

Figure 4 isan enlarged sectional detail showing the gear set from below on the line l -4 of Figurel;

Figure 5 is a sectional detail on the line 5 -23 of Figure 4 Figure 6 shows the portable electric motor;

Figure? shows an alternate form for the pivotshaft "8.

window includes a sheet metal frame preferab'ly of thin stainless steel or aluminum, and a sash or sashes "of correspondin material.

I The frame has a base I, side members 2 and 3, and an upper or top member 4. One or more sashes 5, may be mounted in a, single frame. Each sash is mounted in its appropriate position on coaxial central pivot-shafts 3 and 9 which have their inner ends secured in the sashes at opposite sides thereof.

The top part 10 of the base of the frame is for-med in an arc corresponding to a circle projected upon a radius drawn from the center of the'pivet-shafts 8 and 9.

The lower end H of the sash is curved to correspond with the curvature of the top of the base. The top member 4 of the frame has its lower face curved in the opposite direction and the upper member l2 of thesash is similarly curved.

The bottom frame member or base i has its upper outer part inclined downwardly as shown at 13 to prevent the flow of rain water into the space between it and the bottom of the sash.

The member 14 which is at the bottom of the sash when in either vertical position, has a pro- J'ecting rib [5 formed thereon and extending outward to cause rain water to drip therefrom instead of following the sash into the space between the sash and the top of the adjacent frame member.

The top member 4 of the frame and the top of each crossbar extends outwardly a shortdistance at 16 over the top of the sash and has an inclined projecting rib l! formed at the cute edge thereof to deflect rain water. i

The end members of the sash are formed to conform to the bottom face of the top member of the frame. Both the top and bottom members of each sash are provided with grooves 58 in which weatherstrips I9, preferably of felt, are mounted arranged to contact the adjacent members of the frame.

Where a plurality of sashes is provided, crossbars 20' are mounted in the frame. The upper faces of such crossbars correspond to the upper faces of the frame bases and the lower faces of the crossbars correspond to the lower faces of the top frame members as described.

Similar weatherstrips of felt or other suitable material 21a are mounted in vertical grooves 2i formed in the side members of each sash and the side frame members have their front and rear corners slightly curved or beveled to facilitate the entrance of the weatherstrips and to cause a limited degree of pressure upon them when in closed position.

Thin fiat undulating strips of resilient metal 22 are seated in the grooves for the weatherstrips and arranged to exert a slight degree of pressure outwardly upon the weatherstrips to insure a close fit thereof to the adjacent frame members.

The sashes are mounted upon pivot-shafts B and 9 and are revolvable. The pivot-shaft 8 is a plain round shaft or pivot-pin upon which or with which the sash member revolves. The opposit'e pivot-shaft or pin 9 is preferably rectangular in section and has one end firmly but removably united to the middle of the adjacent shaft is rigidly secured to or formed integral with the gear wheel 23 of a worm gear mounted in a gear box 24 adjustably secured in the side member 2 of the frame.

The pivot-shaft 9 has shoulders formed thereon mounted in suitable bearings formed in the ear box 24.

A transverse worm 25 is revolvably mounted in the gear box in mesh with the gear wheel.

The worm 25 is provided with a rectangular longitudinal bore 26 in which th shaft of a crank 21 may be inserted to turn the worm manually or in which the extended shaft 28 geared to a portable electric motor 29 may be inserted.

The shaft 28 may be extended at both ends of the motor so that either end may be inserted in the bore 26 and thus the worm may be turned in either direction and the window sash turned in either direction to correspond.

Where more than one sash is mounted in a single frame, each sash is provided with corresponding pivot-shafts and the frame is provided with additional corresponding gear boxes with worm gears mounted therein as described.

The upper and lower members of each sash are made with ribs projecting outwardly when in lowermost position a little beyond the outer edges of the adjoining base or intermediate crossbar members of the frames so as to deflect rain or water from other sources and prevent its passage inwardly.

The gear box 24 is preferabl united to its adjacent side frame by machine screws or bolt 39 and may be made adjustable vertically by forming slots 3| in the inner and outer plates thereof whereby when the bolts 39 are loosened from their bores in the frame, the gear box may be moved upwardly and downwardly within small limits for the purpose of adjusting the height of the pivot-shaft 9 and the portion of the sash attached thereto.

Similar means may be utilized for adjusting the height of the pivot-shafts 8. If desired small pins 32 may be utilized to secure the sash to the shafts 8 and 9 and prevent the shafts slipping in the sashes.

The sashes and frames may be secured in fixed relative positions or means maybe provided for vertical adjustment of the gear box and the sash mounted on the pivot-shaft 9 as shown in Figure 5.

Figure '7 shows an alternate form for pivotshaft 8 by which it and the side bar of the sash mounted thereon may be adjusted vertically. In this form the pivot-shaft 9 has an enlarged flat head 8a united thereto with slots 8b formed therein and bolts 8c pass through the slots and are threaded at 8d into bores formed in the frame 3 whereby they may secure the head 8a in adjusted position lengthwise of the window. An annular bearing 5a may be secured in the sash around the pivot-shaft 8.

In the use of my invention the window i preferably assembled by having the frame suitably united at the corners by solder or other desirable means, and laying it in horizontal position upon a flat table or bench. The inner half of the gear box is then placed in its position with the bolts 30 having their heads in the recesses formed for them in the side frames.

The window sash is then laid inside of the frame in its proper place. The pivot-shaft 8 is then placed in itsposition in one of the side bars of the sash 5 and the gear wheel 23 and pivotshaft 9 are placed in the gear box with the pivot 4 shaft 9 extending into the adjacent sidebar of the sash 5 and secured therein as described.

The worm is then placed in its position in the gear box and the gear box fastened at its desired position by tightening the bolts. The heads of the bolts 30 are preferably made square and are seated in beveled square sockets or recesses provided in the side frame so that they may be tightened by the nuts 30a upon the opposite threaded ends of the bolts.

I use the term pivot-shaft to refer to the round shaft 8 on which one side bar of a sash is pivoted as well as to the square-headed or rectangular shafts 9 fitted to the opposite side bar of the sash by which the sash is compelled to revolve when the square-headed shaft is revolved by the worm gear. While I have shown the latter pivot-shaft with a square head fitting into a square bore provided in one side bar of the sash, it is obvious that any form of head maybe used which is fitted to the sash in such a way as to compel the sash to revolve when such pivot-shaft is rotated.

Various modifications may be made in the size, shape and materials of the different parts without departing from the spirit of my invention as expressed in the claims and I do not confine my claims to the precise details shown in the drawings.
